and S3, correspondingly pressing the heat source on the other side of the physiological signal acquisition pad for hot-pressing shaping.
As described in the step S1, the microfiber layer is the outer surface of the physiological signal collecting pad; the PC layer is a shaping body in the physiological signal acquisition pad and can stabilize the shape of the physiological signal acquisition pad; the EVA layer is composed of a plurality of EVA strips arranged at certain intervals, after the microfiber layer, the PC layer and the EVA layer are subjected to hot pressing and shaping to form the face body, the outer side of the face body is a surface with bulges and depressions arranged at intervals due to the arrangement of the EVA strips, and the sensitivity of the physiological signal acquisition pad can be increased. In the hot-pressing shaping process, the hot-pressing shaping time is as follows: t1 is more than or equal to 15 seconds and less than or equal to 25 seconds; the hot-pressing shaping temperature is as follows: t1 is more than or equal to 65 ℃ and less than or equal to 80 ℃. That is to say, the melting point of the hot melt adhesive arranged between the microfiber layer, the PC layer and the EVA is T1 or slightly lower than T1, the temperature T1 is higher than 65 ℃ and lower than 80 ℃, so that the noodle body can be normally used at normal temperature, the hot pressing temperature is not too high, the energy consumption is saved, the time T1 ensures that in the hot pressing project, the heat can be transferred between the layers, the hot pressing effect is ensured, the time can be saved as far as possible, and the production efficiency is improved.

As described in step S3, the heat source is pressed against the other side of the physiological signal acquisition pad to perform the hot press shaping, and since the two side bodies are stacked together and have a relatively large thickness, the hot press shaping is not performed on only one side, so that the hot press shaping is performed on the other side body, thereby improving the adhesion stability between the two side bodies and the sensing film. In this step, the hot-press shaping time is as follows: t3 is not less than 15 seconds and not more than 20 seconds, so that the heat is transferred to the position with slightly poor hot pressing effect in the step S2, and the integral hot pressing effect of the belt body is improved; the hot-pressing shaping temperature is as follows: t3 of more than 65 ℃ and less than 70 ℃, and the hot pressing temperature T3 is the same as the T2, so that the sensing film can not be damaged by the temperature under the hot pressing temperature, and the production yield of the physiological signal acquisition pad is improved.

and step S23, testing whether the sensing film welded with the copper wire works normally, if the sensing film works normally, putting the sensing film into a station to be produced, otherwise, putting the sensing film into a station to be maintained. If the copper wire can not work normally after the sensing film is welded, the sensing film needs to be selected for maintenance and other treatment, the production of bad physiological signal acquisition pads is reduced, and the production yield is improved.
